The fatty acid group of the fatty acid amide consists of an alkyl group having 14 to 30 carbon atoms. The ratio of epoxidized non-higher fatty acid amide to fatty acid or fatty acid salt in the acid-sized and diluted pulp is 0.01:1-0.2:1.

When an alkyl ketene dimer is additionally used, the ratio of 7t'th fatty acid amide to alkyl ketene dimer to fatty acid or fatty acid salt during epoxidation is 0.02:0.2:
The total amount of epoxidized higher fatty acid amide added to the size mixture used according to the invention is 0.01 to 0.15 : 0.4 : 1 with respect to the pulp.
~0.6% by weight. Epoxidized higher fatty acid amides are added to the pulp in an amount of less than 0.01% of the pulp, so that the penetration of the photographic bath into the paper is not sufficiently hindered. When the amount of epoxidized fatty acid amide is increased above 0.31% by weight with respect to the pulp, the paper loses its internal strength, which has a detrimental effect on the font properties of the photographic layer.

Surprisingly, FFJK also shows that the further addition of anionic and cationic polyacrylamide does not result in strong agglomeration of the fibers, but rather in a highly smooth surface of the paper and at the same time a strong increase in internal strength. It has been shown that the increase in strength is not only temperature dependent. In general, all used polyacrylamide-combinations show a #& dependent increase in internal strength! -, but this strength benefit is different for the same dietary supplement, the same quantity ratio and the same chain length of polyacrylamide. It depends on the acrylate proportion of the polyacrylamide, but this is not an IEI-like dependence, ie the highest value of internal strength is not achieved with a high proportion of anionic groups. This is rather obtained if the proportion of anionic groups in the anionic polyacrylamide is between 5 and 20%.
